Claims.

This invention relates to containers, or receptacles, of the type used in connection with the retail of merchandise in small quantities. These containers are usually formed of paper, or simi- 5 lar fibrous material, and are used in connection with the sale of ice-cream, and similar products.

The general object of my present invention is the provision of a removable sub-compartment end closure for such a container. In connection with the sale of certain products, such as icecream, the customer often purchases one or more other products such, for example, as syrups to be used in connection with the ice-cream, or product being purchased. My removable subcompartment end closure provides a separate compartment, or space, for such additional product, and a further object of my invention is a sub-compartment removable end closure of particularly simple and economical construction,

and which can be conveniently filled, sealed and adapted to the main body of thecontainer."

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views. I I

Figure 1 is an elevationalyiew' showing a preferred embodiment of my detachable sub-compartment end closure applied to a container and being partly'in section.

. Figure 2 is an exploded view of the main elements comprising the end closure, illustrating the manner in which the end closure is assembled.-

The invention consists generally of the combination of a conventional tubular receptacle and a detachable sub-compartment end closure, which consists of a cup shaped member with the flange, or side portion, of said member complemental in cross section to the body of the container, and which is encircled by a band extending beyond one end of thef cup member and frictionally engaging the open end of the receptaole. The sub-compartment is formed by a disk of thin, flexible material, such as cellophane, being arranged over the open end of the end closure after the contents has been placed'therein, and with the periphery of the sheet extendmg between the outer surface of the flange of thecup shaped end closure and the band.

A conventional type of container'is illustrated in Figure 1, and comprisesia tubular body portion I0, usually circular in cross" section, and

provided with a bottom closure 'Il which is secured to the body II] by the conventional crimp} as at I2, or in any other suitable manner.

The removable end closure comprises a cup shaped member formed by a discoidal portion I3, to the periphery of which is secured a band or 5 flange member I4. These elements may also be secured together as by crimping, as at I5. The flange member I4 is complemental, in cross sectional dimension, to the tubular body III of the receptacle. After the receptacle is filled with 10 ice-cream, for example, the end closure is inverted, as shown in Figure 2, and the syrup, or other desired product, placed therein. Subsequently, a disk or sheet I6 of thin, flexible material, such as cellophane, is arranged over the 15 open end of the end closure, and a sleeve or band I! is pressed axially of the end closure, by which action the peripheral portion of the sheet I6 is folded downwardly about the outer surface of the flange Id. The sleeve I1 is preferably of 20 appreciably greater length than thelength of the flange I4, and extends outwardly beyond one end of the flange. The outwardly extending portion of the band Il frictionally encircles the upper. end of the body I0, whereby the end 010- 2 sure, after the same has been filled and assembled, may be applied to the container in the same manner as the. conventional slip cover with the sheet l6 arranged inwardly, as shown in Figure 1, or outwardly to provide a window 30 through which the contents of the end closure may be inspected. In the latter instance, the sleeve'or band I! would be pushed farther on the flange I 4, so that the sleeve would extend be yond the opposite end of the flange. 35

The inner diameter of the sleeve or band 'I1 is such as to tightly engage the flange I4 and accordingly, the peripheral portion of the. disk I6 is securely clamped between the flange I4 and the sleeve I1. I have found that'if the parts of 40 the end closure are proportioned approximately, as illustrated in Figure 1, the sheet I6 is secured to the end closure in liquid tight relationship, and will not leak with thin liquids, such as water, over a period of several hours. 45

If preferred, the inner surface of. the sleeve [1 may be formed or provided with inwardly extending ribs 20, 2|, the ribs 20 being preferably spaced equal distances from the ends of the sleeve I1, and the rib 2| bein'garranged midway 50 between the ends of the sleeve. In this instance, the sleeve I1 is of slightly greater diameter than the body III and the flange I4. withlthis arrangement, the sleeve I! may be more easily pressed over the marginal portion of the disk I6, 55

and the flange I4, and the end closure more easily a plied to the end of the body I0. With this arrangement, the ribs 20 frictionally engage the body III to form a tight, liquid ,prooi'. joint, regardless of which end of the sleeve I! extends beyond the flange I4 and the intermediate rib, 2| tightly presses the flange of the disk l6 against the outer surface of the flange ll forming a liquid tight joint between these members.

Preferably, the sleeve I1 is provided with one or, more small apertures 22 arranged between the rib 2| and ribs 22. The purpose of these apertures is to permit the escape of air from within the extending portion of the sleeve I'I while it is being pressed on the end of the body I.

It will be observed that should the customer desire to purchase a quantity or. syrup to be used with the ice-cream contained in the receptacle, the clerk or attendant can quickly and conveniently fill the end closure with syrup, lay the sheet l6 over the open end thereof and press the sleeve l1 over the flange I 4', and when thus assembled the unit comprises an end closure for the container.

It will be understood and appreciated that there are a number of instances where it is desired to package two products, which are generally used together, in one package, and my removable sub-compartment end closure is particularly adapted for such use.

What I claim is:

1. The combination of a receptacle having a tubular body portion and a removable sub-compartment end closure for one end of said' body, said end closure comprising a discoidal portion having a depending annular flange complemental to said tubular body, with the edge of the flange abutting against the end of the body portion, a band encircling said flange and the end portion of said body, and a disk of thin, flexible material arranged over the open end oithe flange and being secured at its periphery between the outer side of said flange and the inner surface of said band.

2. The combinationof a receptacle having a tubular body portion and a detachable sub-compartment end closure "forthe receptacle, said end closure comprising a cup shaped member arranged with its open end abutting against the end of the body portion, a band encircling said tubular body portion forming a main compartment, anda detachable end closure forming a sub-compartment, said end closure comprising a discoidal portion having a depending annular flange secured to its periphery, a sheet of thin,

flexible material arranged across the open end of said flange, with the peripheral portion of said sheet overlapping the outer surface of said flange, a band encircling said flange and peripheral portion of said sheet, and having a portion extending beyond said flange and frictionally engaging the end of the body portion, and said band being provided with an aperture adjacent the open end of said flange to permit the escape of air when said end closure is applied to the end of the body.

4. The combination of a receptacle having a tubular body portion forming the'main compartment of. the receptacle, and a detachable end closure forming a sub-compartment, said end closure comprising a cup shaped member, a sheet of thin, flexible material arranged across the open end of the cup shaped member, with a periphery of said sheet folded about the outer side of said member, and'a sleeve frictionally encircling the outer side of said member and securing the periphery of said sheet between the sleeve and said member, and said sleeve extending outwardly beyond the open end of said member and arranged to frlctionally encircle the open end of the body portion.

5. The combination of a receptacle having a tubular body-portion and a detachable sub-compartment end closure for the receptacle, said end closure comprising a cup shaped member formed 7 of relatively stifi fibrous material, a band encircling the periphery of said cup portion, a sheet of thin, flexible material arranged across the open end of the cup member and being secured at its periphery between said cup member and said'band, and said band extending beyond one end of said cup member with the extending portion encircling the end portion of the body of the receptacle.
